A superhydrophobic coating is a thin surface layer that repels water. It is made from superhydrophobic (also known as ultrahydrophobic) materials, and typically cause an almost imperceptibly thin layer of air to form on top of a surface. Droplets hitting this kind of coating can fully rebound. [ 1 ][ 2 ] Generally speaking, superhydrophobic ...
A) A superhydrophobic surface with a high contact angle nearing 180 degrees. B) A surface with a low water sliding angle. C) A surface with a higher sliding angle which will be less efficient when self-cleaning water from its surface. Control over surface wettability is a critical aspect of self-cleaning surfaces.
Antimicrobial surface. An antimicrobial surface is coated by an antimicrobial agent that inhibits the ability of microorganisms to grow [1] on the surface of a material. Such surfaces are becoming more widely investigated for possible use in various settings including clinics, industry, and even the home. The most common and most important use ...
A water drop on a lotus surface showing contact angles of approximately 147°. The lotus effect refers to self-cleaning properties that are a result of ultrahydrophobicity as exhibited by the leaves of Nelumbo, the lotus flower. [ 1 ] Dirt particles are picked up by water droplets due to the micro- and nanoscopic architecture on the surface ...
Superhydrophobic surfaces, such as the leaves of the lotus plant, are those that are extremely difficult to wet. The contact angles of a water droplet exceeds 150°. [ 6 ] This is referred to as the lotus effect , and is primarily a physical property related to interfacial tension , rather than a chemical property.
Ultrahydrophobicity. A drop on a lotus surface, with a contact angle of greater than 146°. A water droplet falling onto a superhydrophobic, elastic surface. In chemistry and materials science, ultrahydrophobic (or superhydrophobic) surfaces are highly hydrophobic, i.e., extremely difficult to wet. The contact angles of a water droplet on an ...
Unfortunately, in the case of going to bed with wet (or even damp) hair, the downsides might outweigh the benefits. It turns out, going to bed with wet hair can cause serious issues with not only ...
Hydrophobins are a group of small (~100 amino acids) cysteine -rich proteins that were discovered in filamentous fungi that are lichenized or not. Later similar proteins were also found in Bacteria. [ 1 ] Hydrophobins are known for their ability to form a hydrophobic (water-repellent) coating on the surface of an object. [ 2 ]
